Description

Technical Field

[0001] This utility model belongs to the field of automotive front bumper tooling technology, specifically a tooling for detecting missing parts of automotive front bumper components. Background Technology

[0002] As a crucial safety component for vehicles, the technological development of the front bumper is closely linked to the improvement of vehicle safety performance. With the development of the automotive industry and the increasing safety standards, bumper technology has gradually evolved towards lightweighting and energy absorption. Since the 21st century, high-molecular composite materials, represented by polypropylene (PP), have become mainstream. Combined with energy-absorbing structural designs such as honeycomb and foam layers, they can absorb energy through material deformation during low-speed collisions, reducing vehicle damage. Simultaneously, the introduction of pedestrian protection concepts has led to the use of softer cushioning materials at the front edge of the bumper, along with optimized installation height and curvature, reducing impact injuries to pedestrians' legs.

[0003] CN201920388175.2 discloses a front bumper internal support device, including an integral strip-shaped support body. The support body includes a first mounting plate, a connecting plate, and a second mounting plate. The connecting plate is connected to the first mounting plate and the second mounting plate respectively. The first mounting plate and the second mounting plate are located on opposite sides of the connecting plate. The middle part of the first mounting plate is connected to the front bumper skin, and both ends of the first mounting plate are connected to the front bumper suspension. The second mounting plate is provided with a plurality of water tank frame mounting points, and the second mounting plate is connected to the water tank frame through the water tank frame mounting points and bolts.

[0004] The above-mentioned technical solution mainly discloses the structure of the front bumper. When the front bumper is assembled with other parts, it is usually fixed with multiple screws. However, in practice, it has been found that during the assembly process, due to the assembly steps and the large number of materials, it is easy for screws to be missing or insufficient, which makes the parts easy to loosen. Therefore, workers need to repeatedly check the points. However, this inspection method is very troublesome, prone to omissions, and increases the fatigue of workers. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] refer to Figures 1-4 A tooling for detecting missing parts of a car front bumper assembly, the front bumper assembly including a front bumper 7 and an accessory 101 bolted to the front bumper 7;

[0033] The tooling includes a workbench 1, a positioning module 3 and a horizontal drive module 2 mounted on the workbench 1; the positioning module 3 is used to place the front bumper 7; the horizontal drive module 2 is equipped with a clamping mechanism 8 and a lifting unit 4.

[0034] The horizontal drive module 2 is used to drive the clamping mechanism 8 to clamp the front bumper 7 against one side of the positioning module 3 and to position the lifting unit 4 above the accessory 101.

[0035] The lifting unit 4 is provided with a clamping member 6 and a detection component 5. The lifting unit 4 is used to drive the clamping member 6 and the detection component 5 downward so that the clamping member 6 clamps the accessory 101 and the detection component 5 contacts the bolt to detect the presence of the bolt.

[0036] In this design, the worker first places the front bumper 7 on the positioning module 3 of the workbench 1, then installs the accessory 101 onto the front bumper 7 with bolts. Next, the horizontal drive module 2 is activated. Driven by the horizontal drive module 2, the clamping mechanism 8 clamps the front bumper 7 against one side of the positioning module 3, positioning the lifting unit 4 above the accessory 101. Then, the lifting unit 4 drives the pressing component 6 and the detection component 5 downwards, causing the pressing component 6 to press the accessory 101 firmly and the detection component 5 to contact the installed bolts to detect their presence. After the detection is complete, the lifting unit 4 and the horizontal drive module 2 are reset. This method utilizes the detection of missing or insufficient parts during assembly, and the cooperation of the clamping mechanism 8 and the pressing component 6 ensures that the front bumper 7 and accessory 101 do not shift during the detection process, thus avoiding displacement during testing.

[0037] Preferably, the horizontal drive module 2 includes a base plate 22, a fixing frame 23 disposed on the top of the base plate 22, a rodless cylinder 21 disposed on the worktable 1, and a guide rail 24, wherein the base plate 22 is connected to the guide rail 24 and the rodless cylinder 21;

[0038] The clamping mechanism 8 is mounted on the base plate 22, and the lifting unit 4 is mounted on the fixed frame 23.

[0039] Specifically, the rodless cylinder 21 provides power output, which drives the base plate 22 to move, thereby moving the fixed frame 23. This causes the clamping mechanism 8 to clamp the front bumper 7, and allows the lifting unit 4 on the fixed frame 23 to move above the accessory 101.

[0045] Specifically, when the lifting cylinder 41 is used to output power to check the bolts of the accessory 101, the lifting cylinder 41 drives the fixing plate 42 to move downward, thereby causing the first pressure block 62 and the metal induction switch 52 on the connecting rod 61 to move downward. Then, the first pressure block 62 presses the shawl tightly, and the metal induction switch 52 contacts the bolt to detect whether the bolt is present. When the bolt is missing, the alarm light 51 flashes to alert the worker, and then the worker can check.

[0046] Preferably, the workbench 1 is further provided with a pressing cylinder 9, and a second pressing block 91 is provided on the output end of the pressing cylinder 9. The pressing cylinder 9 is used to drive the second pressing block 91 downward to press the middle part of the front bumper 7.

[0049] In practical applications, there are two parts 101, and the two parts 101 are respectively located at both ends of the front bumper 7; there are two horizontal drive modules 2, and the two horizontal drive modules 2 correspond one-to-one with the parts 101.

[0050] Furthermore, when the worker needs to assemble the front bumper 7 and the accessories 101, the worker first places one end of the front bumper 7 on the first contouring part 311 of the first positioning component 31, the other end on the third contouring part 331 of the third positioning component 33, and the middle part on the second contouring part 321 of the second positioning component 32. Then, the middle part of the front bumper 7 is pressed by the clamping cylinder 9. Then, the two accessories 101 are installed on both ends of the front bumper 7 by bolts. After the installation is completed, the horizontal drive module 2 first drives the clamping component to clamp the front bumper 7, and then the lifting unit 4 drives the clamping component 6 and the detection component 5 to move down. The clamping component 6 clamps the front bumper 7, and the detection component 5 detects whether there are any missing or insufficient bolts installed.

[0051] In this embodiment, the accessory 101 is mounted on the front bumper 7 by multiple bolts, and the number of metal sensor switches 52 corresponds one-to-one with the number of bolts.

[0052] Furthermore, each metal sensor switch 52 corresponds to a bolt. When a metal sensor switch 52 does not contact a bolt, an alarm light 51 flashes to alert workers to investigate.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
